Hi,
I'm trying to put a CADET PC Radio on Linux 2.2.16 in order to stream a
local radio station. Actually when I compile 2.2.16 with its support, PnP
doesn't find it. But, when I compile it with radio-cadet as a module, and
load it, it seems to find the card, but I can't hear anything on the card
output (I've already tried some V4L app such as rtune, gradio, libradio).
See...
# insmod radio-cadet
Using /lib/modules/2.2.16/misc/radio-cadet.o
# dmesg | tail -1
